Damien Neil 170b2bfca6 internal/impl: precompute required bit in validator

Required field validation populates a bitmask of observed required
fields. Store a uint64 containing the bit to set in the validationInfo
rather than the index of the bit. Provides a noticeable speed increase
in validation.
